Answer 2

Answer:

Starting position of mine shaft is = 10m above ground

but,

it moves in opposite direction so it travels the distance (-350 m ) below the ground.

Total distance covered by mine shaft = 10m - (-350m)

$= 10 + 350$

$= 360m$

Now, taken to cover a distance of 6m by it = 1 minute

Time taken to cover a distance of 1m by it =

$\frac{1}{6\ }\min$

Therefore, tie taken to a cover a distance of 360m =

$\text{60 minutes = 1 hour}$

thus, in one hour the mine shraft reaches = 350 below the ground.
